Overview

Write and preview HTML in real time

This live HTML editor renders your markup instantly beside the code, so you can prototype layouts, test snippets, and learn by experimenting without setting up a project. It's ideal for quick edits, teaching, and validating a component before dropping it into a larger codebase.

FAQ

Frequently asked questions

How do I test HTML code online for free?+

Type or paste your HTML into the editor panel. The live preview updates in real-time on the right side, showing exactly how your code renders in a browser. No signup required.

Can I include CSS and JavaScript in the HTML editor?+

Yes. Write your full HTML document including inline CSS (<style> tags) and JavaScript (<script> tags). Everything renders in the live preview just as it would in a real browser.

How do I beautify HTML code online?+

Paste your messy or minified HTML and click the 'Beautify' button. The editor automatically adds proper indentation, line breaks, and formatting to make the code human-readable.

Can I export my HTML code as a PDF?+

Yes. Click the PDF export button to convert your rendered HTML page into a high-fidelity PDF document. This is useful for generating reports or documentation from HTML templates.

Is my HTML code saved anywhere?+

No. All code runs locally in your browser. Nothing is sent to our servers, so your code stays completely private.

Can I use this HTML editor to learn HTML as a beginner?+

Yes. The live preview is ideal for learning — type a tag and immediately see the result. Start with basic structure (<h1>, <p>, <a>), then experiment with inline CSS. The instant feedback loop is much faster for learning than editing a file and refreshing a browser tab.

Can I include CSS and JavaScript?+

Yes — add inline <style> and <script> in your HTML and the preview renders them live.

Is my code saved anywhere?+

No. Everything runs in your browser; nothing you write is uploaded.
